Persevere datasource driver - postgresql

Question

I'm new to persevere, I did the helloWorld tutorial, very impressive btw but I'm now trying to connect to a real postgres database and find myself struggling having the driver recognized when I have the feeling it should be dead simple.
I dropped all the jdbc driver for postgres I had to the persevere/lib folder:
postgresql-8.3-603.jdbc2ee.jar
postgresql-8.3-603.jdbc2.jar
postgresql-8.3-603.jdbc3.jar
postgresql-8.3-603.jdbc4.jar
And yet when I start persevere with the command "persvr" with no argument from my project folder I get the following error message:
java.lang.ClassNotFoundException: org.postgresql.Driver

I'm actually trying to expand the helloWorld project as an exercize, so I've added a postgres.json file in my helloWorld/WEB-INF/config folder. Here is the content of that file:
{"id":"postgres.json",
"sources":[
{"name":"addressTable",
"sourceClass":"org.persvr.datasource.DatabaseTableDataSource",
"connection":"jdbc:postgresql://hostname:5432/pnp?user=user1&pass=mypassword",
"driver":"org.postgresql.Driver",
"camelCaseColumnNames": false,
"table":"addr",
"idColumn":"addr_id",
"dataColumns":["addr_stat_cd","addr1","addr2","city","state","zip","zip_ext","cntry_cd","last_upd_uid","last_upd_dttm","create_uid","create_dt
tm"],
"schema":{
"data":{"$ref":"../addressTable/"}
}
}]
}
Could anyone tell me why persevere can't find that postgres driver please?
Thanks,
Lancelot.

Answer 1

Figured it out. The postgres driver jar should actually go into the folder: persevere/WEB-INF/lib instead of the persevere/lib.
